Tov @ZZ whom concern.-

Be it known that I, HUBERT M. PERRY, a at no1s, have inventedcertam newand useful Improvements in Side Bearings for Cars, of which' thefollowing is a speciiication.

This invention relates to improvements in side bearings oftheantifriction type, and

has for its objectto provideimprovements in thel details ofconstruction, the same general type of side bearing being shown anddescribed in my prior patent,l No. 806,360, issued December 5, 1905.

The objects of the invention, more speciiically stated, are to provideaconstruction in which a singlepiece casting forms at once a;completehousing of the antifriction-rollers in so far as the latter arein'closed, to provide an improved construction which enables the rollersorl supporting-wheels to. be seated within the housing with smallportions only oftheir peripheries protrudingwitho'ut providing aremovable top for the housing, to provide an improved construction whichenables the base ofthe accommodate itself to the su porting-timber u onwhich it is mounted an avoids liability ci) breaking the bearing byreason of inac'cu rate fitting ofthe base to its support, to prov vide asim le and eiiicient means for securing in the matters hereinafterdescribed, andy the j ourna -pins upon which the supportingrollersrotate in place withput resorting to threaded or other expensiveconnections, and in general to provide an improved construction of thecharacter referred to.v

y To the above ends the invention consists more articularly pointed voutin the appended) claims. l

The invention will be readily understood from the following description,reference being had to the accompanying drawing, in which* Figure 1 is aplan view, with parts in hori zontal section, taken in a .planecoincident with the axis of the journals of a preferred embodiment ofthe invention. Fig;` 2 isl a view partly in side elevation and partly incentral longitudinal vertical section. Fi 3 is a transverse verticalsectional view ta en throu h the axis of one of the main supporting-weels. Fig. 4-is a vertical section on bearing to more readily` line a. bof Fig. 1, omitting the roller and its ,journal-pin.

Referring to said drawing, l designates as a whole a.boxlike base membermade open at its lower or base side and provided4 with an integral topor cover portion 2, suitably apertured, as indicatedat 3 3, to permitthe peripheral portions of the main supportingrollers 4 to preferredconstruction shown the main casting is provided with laterally-oppositehorizontally-projecting extensions 5, which are epertured, as indicatedat 6, to receive the bolts, whereby the bearing is secured to its suport.

he main supporting rollers or Wheels 4, of which there aretwo, aremounted upon cylindric journal-pins 7, which are arranged with theiraxes inclined sli so'as to respectively coinclde with radii from thepivotal center of the truck. -As a novel feature of construction each ofthese journal-pins is arranged to extend entirely through one side ofthe housing, as indicated protrude therethrough-` In. the

ghtly to each other, i

at 8, and into a socket 9 in the opposite side of the housing, whichyextends only partly `through the side wall thereof. At the points wherethe journals are seated in the side Walls of the housing the latter arethickened or provided V which serve the double purpose of affording alarger bearing for the journal-pin and of confining the .supportingrollers or wheels 4 against endwise movement.

The interior of each supporting-wheel is larger than the journal-pinupon which it is supported, and. a series of small cylindric rollers 17is arranged to occupy the space between said parts and constituteroller-bearings between the same. small rollers is slightly less thanthe axial length of the main wheel or roller within which they arearranged,

fine the small rollers in position Washer-like plates 11 are seated ineach end of the larger roller concentric with the journal-pin, as seenclearly 1n Fig. 3.

The journal-pins ,7

are fxedly seated in the housing and are con` veniently fastened inposition by forming a small -recess in the peripheral portion of the`outer end of after the pin is' seated in the housing the adjacentperimeter oi`l 'the aperture is peened The length of the the pin, asindicated at 12, andwith annular ribs I0,

and in order to con- IOO ' down into the recess 12, asindicated at '13of in position. .once to lock the journal-pin against rotation Fig.2,*so as to, in`eifect,rivet the journal-pin This simple expedientserves at and to hold it against' endwise movement Withinits seat..

vAs a further detail of improvement make the peripheries of the mainsupporting-rollers 4 convexin cross-section, as best seen in' the'sectional view, Fig. 3. Preferably-this `con'- vexity is provided byforming/the periphery of each Wheel .With a central narrow cylindricportion 14 and -inclimng the remaining 'surv1lacesof the periphery toform slightly-conical surfaces' 15. The object of this construction isto insure al vbetter distribution v of the Weight upon the Ijournal-pinsand in this manner betterldistributethe Weight to the mainsupporting-casting. I

The ,fcon'struction describedv has, iamong others,the'followingadvantages, namely: It 1 vdispensesl With the necessity of making a re.-

movable top plate for-the housing, thereby lesseningthe cost, ,and .italsoprov'ides acon- 'vexA or turtlefback.' housing upon `Which dirt anddetritus-'arenot llikely to accumulate. It provides amplespacefor alldust and dirt to accumulate in theybottom of the housing Without.interfering with the 'freedom of movement of the supporting-Wheels, andwhen thehousing or base member'is supported upon a timber which isapertured-to correspond with the open bottom of the lhousing, as Willusually be thev case, the dust andl dirtv fall through Without lodging.The parts may the latter, and in generalthe construction is such as toafford high e'fiiciency at a minimum cost.

Mesos I claim as my invention-- l. A side vbearing for cars comprising abox-like base member 'provided with an integral cover portion. aperturedfor the-periphery of-'the' main supporting-roller and having an openingat itslower'side through which the mainl roller may be inserted, a

journal-pin mounted thereon, and an openended main roller mounted uponsaid journal 'and having its periphery protruding through and above thecover .portion of the housing, a

'series of rollers mounted Within said main roller-'around saidjournal-pin, and a pair of f 'Washers mounted' within the ends of saidmain roller concentricallywith the journal-f pin and confining thesmaller rollers.

'Y 2. A. side bearing for cars comprising a,

box-like base member provided with an inte-' gral cover portionapertured for the periphery of the mainsupporting-roller-and'having anopening Vat its lower side through-Which the main roller may beinserted, a journalpin mounted thereon, andan open-ended main rollermounted upon said journal and above thecover porti-on ofthe housing,said journal-pin being inserted through one .side of the housing andinto-but not through the opposite side ofthehousing, and suitable means/for confining said journal-pin immovably in place."

`3. A side bearing for cars', comprising a box-like base member4provided with lan iiitegralv cover-*portion apertured for .theperiphery ofthe main supporting-roller and having an opening in .itslower side through having its periphery protruding, through and. i

which saidmain roller may be inserted, said base memberl havingcomparatively light side .WallsL thickenedl vjournal-pin bearings4formed integral with the opposite side Walls in axial alinement, saidthickened bearings being formed by 'inwardly-projecting annular bosses.;and a journal-pin, the lends of which are seated within said thickenedbear# ings.
